Katrina Vanden Heuvel, The Nation Magazine joins Thom Hartmann. For tonight’s Conversations with Great Minds - we’re going to take a closer look at the momentous decision by the Obama administration to normalize relations with Cuba. First announced on Wednesday - the move - which came after months of secret negotiations - is the most significant shift in American foreign policy towards Latin America in decades. Not surprisingly - it’s also causing a lot of controversy back here in the U.S. - with many Republicans slamming the president for what they say is another example of his “weakness” But what's the real deal with America's new policy towards Cuba? And who stands to benefit most from the end of one of the last remaining Cold War standoffs?
